Hello,
I'm seeing seemingly unneccessary resource restarts with heartbeat-2.1.3
(Centos RPM 2.1.3-3.el5.centos) on RHEL5 and a quite current Debian
testing (heartbeat package 2.1.3-3).
I have a location constraint like this:
<rsc_location id="ms-drbd-srv:connected" rsc="ms-drbd-srv">
<rule id="ms-drbd-srv:connected:rule" role="master" score_attribute="pingd">
<expression id="ms-drbd-srv:connected:expr:defined" attribute="pingd"
operation="defined"/>
</rule>
</rsc_location>
It's supposed to force the master of the drbd resource onto the machine
which has the best connectivity to its ping nodes. This works nicely: The
resources will fail over to the node with the highest pingd attribute
value.
But: Whenever a ping node changes status on all cluster members
simultaneously (for example because of a switch reboot) all resources
are restarted once.
Is this expected behaviour?
Can it be prevented?
Thanks in advance,
